Rules Governing Initialization Parameter Files

The following rules govern the specification of parameters in initialization parameter files:
■ An initialization parameter file should contain only parameters and comments. A
pound sign (#) starts a comment line. The rest of the line is ignored.
■ You can specify parameters in any order.
■ Case (upper or lower) in filenames is significant only if case is significant on the
host operating system.
■ To enter several parameters on one line, use spaces between parameter names and
values, as in the following example:
PROCESSES = 100 CPU_COUNT = 1 OPEN_CURSORS = 10
■ Some parameters, such as ROLLBACK_SEGMENTS, accept multiple value entries.
Enter multiple values enclosed in parentheses and separated by commas. For
example:
ROLLBACK_SEGMENTS = (SEG1, SEG2, SEG3, SEG4, SEG5)
Alternatively, you can enter multiple values without parentheses and commas. For
example:
ROLLBACK_SEGMENTS = SEG1 SEG2 SEG3 SEG4 SEG5
Either syntax is valid.
If you enter values for one parameter in multiple entries, then the entries must be
on consecutive lines. If they are not, then the first entry will not be processed
properly. For example, in the following entry the setting for SEG3 and SEG4 will
override the setting for SEG1 and SEG2:
ROLLBACK_SEGMENTS = SEG1 SEG2
OPEN_CURSORS = 10
ROLLBACK_SEGMENTS = SEG3 SEG4
■ A backslash (), also known as an escape character, indicates continuation of the
parameter specification. If a backslash continues a line, then the continued line
must have no leading spaces. For example:
ROLLBACK_SEGMENTS = (SEG1, SEG2,
SEG3, SEG4, SEG5)
■ You can use the IFILE initialization parameter to embed the contents of another
initialization parameter file into the current initialization parameter file.
■ Enclose in quotation marks any parameter values that contain spaces or tabs. You
can use either single or double quotation marks unless otherwise indicated. For
example:
NLS_TERRITORY = 'CZECH REPUBLIC'
■ Enclose in quotation marks any parameter value that contains a special character.[@more@]
